Specification of Letters Patent.

Patented March 16, 1909.

Application filed January 11, 1908. Serial No. 410,383.

To all whom it may concern:

Be it known that we, CHARLES E. KRUEGER and VViLLiAM H. KRUEGER, both citizens of the United States, and residents of'Minneapolis, in the countylof Hennepin and State of Minnesota, have invented a new and Im- `)roved'ltiagazine T alking-Machine, of which the following is a full, clear, and exact description.

Our invention relates to talking machines, our )urpose being to produce a device in whic a large number of distinct oper-ations are performed automatically, so that the machine requires a minimum of attention.

To this end our invention embodies thel following objects: I. To provide a magazine for holding` a number of separate records and means for changing these records so that they are played in a predetermined order of succession, the substitution of `one record for another being made automatically by the machine. II. Toprovide mechanism whereby a needle, when used upon one record may be discarded and a new needle substituted for use upon the next successive record, the substitution of this needle being erformed automatically by the machine. I I. To-enable the operator, by an adjustment of certain parts of the machine, to change the action thereof so that each record maybe played twice in succession before the substitution of another record, and each needle may be used twice before the substitution of another needle. IV. To enable certain parts to. be disengaged from the main apparatus, thereby enabling any record or records to be repeated as many times as desired, new needles being substituted automatically for those already used.

"V. To enable the magazine of the machine to changed automatically,

be adjusted so as to accommodate large or small records as desired.. VI. To enable certain partsof the machine to be thrown out of action -at will so that the records may be a single needle being used to operate upon all of the records in succession. f

. Reference is to be hadlto'the accompanying'drawings forming a part of this specification, in which similar characters vof reference indicatecorresponding parts inallthe iigmachine,this view showing atthe right the phonographic horn, at Aits top 'a number of disk records t`o be-dropped one at a time upon the turntable, and showing at itsmiddle'and.

Standards 25, 25aL having a plate 26 vintegral therewith together constitute the main frame. Standards 27, 28 are mounted upon the main frame and project upwardlytherefrom. The main shaft is shown at 29 and is f provided with a handle 30 whereby it may be turned.- Mounted rigidly upon the main shaft 29 is a sprocket gear 31 and engagingy this s rocket gear is a sprocket chain 32. A sproc et gear 33 likewise engages the chain 32. A bracket 34 (see Fig. 2) is rovided with a slot 35 and extending throu the slot 1s a screw 36 en aged by'a nut 37. y loosening the nut 37 y hand, the bracket may be adjusted by moving it to the right or to the left accordin to Fig. 2, and when the adjustment is comp ete the nut 37 may be tightened.

An idle sprocket gear 38 is revolubly mounted upon the bracket 34 and engages the sprocket chain 32. the bracket 34 adujstable is to regulate the tensionof the sprocket chain. Just below the idle sprocket gear 38 is a pawl 39 mounted upon a crank 40, the latter being rigid upon the main shaft 29. A spiral spring 39a extends from this pawl to a pin 39h, mounted upon the crank collar 39, see Fig. 17. A ratchet wheel 41 is likewise mounted rigidly upon the main shaft and is engaged by the pawl 39. The pawl is to prevent backward turning of the main shaft 29.

A main spring (see Fig. 6) is shown at 42 and is connected at one of its ends with a stationary pin 43 its other end being secured to the main shaft 2'9. This pin is mounted within a casing 44 which protects the spring. Whenever the main shaft 29 is turned by aid of the hand crank 30,- the main spring 42 is wound up, and the main shaft 29 is unable to turn backward for the reasons above stated. A revoluble shaft 45 is provided with a gear 45a having a hub 46 and being rigid relatively to the shaft. Mounted rigidly upon the gear 45a is a cam 47 provided with a notch 48. This cam, except for the notch 48, is annular in shape. Disposed below the wheel45a and meshing therewith is a pinion 49 mounted rigidly upon a stub shaft 49a. A worm gear 50 is also mounted rigidly upon this stub shaft. This worm This governor is provided with a friction disk 53 and with a shoe 54 secured in position by aid of a screw 55. By aid of the screw 55 the shoe 54 may be adjusted, within reasonable limits, to any desired elevation upon the standard 27, the governor being thus set for different speeds. Hence, by adjusting the shoe 54 the speed of the entire apparatus may be controlled at will. Y

A wooden casing is shown at 56 and supported upon it are two bars 57, and across them extends a bar 57a. Extending obliqu'elyupward from the bars 57, is a brace 58. Opposite this brace and mounted upon the main frame is an upper frame 59. A fiat bar 60 is secured to the brace 58 and is provided with bent being secured upon the top of the upper frame 59. Mounted upon the -under side of the bar 60 is a supporting bracket 62 held in osition bya screw 63 Which passes throug 4a slot 64. The bracket 62 isadjustable relatively to lthe bar 60 by aid of this slot and screw. Another bracket 65 is disposed upon the under side of the bar 60 and 1s providedwith a body portion 66 held agairst the bar by aid of a bolt 67. The bar 60 is with holes 60, 601 for the purpose ol making Our purpose in rendering gear engages a revoluble -Worm 51 forming a part of a governor 52.

rovided v 13u mounted upon the portion 61 of the bar 60 and mounted upon these lug? is a pivot pin 94. A lever 95 is supported y this pivot pin and is provided with a portion 96 which extends obli uely upward through a portion 92a to the sli e 92. Whenever' the lever 95 is caused to rock, the slide 92 reciprocates and thus allows the gradual-rotation of the shaft 83. The pawl 86 and slide 92 withI their accompanying parts thus constitute -an escapeinent. f

Record disks are shown at 97, 98, 99 and are supported by the different convolutions of the thread 84. The rod 75 extends through all of these disk records. Whenever the lever 95 gives one up stroke and one down stroke, the escapement is operated in such manner that the thread 84 forms one complete revolution and this releases the lowermost record disk which in this instance is the one marked 99. The record disk being released simply follows the rod 75 downwardly, and the upper portion of the shaft 72, and rests upon the turntable. The lever certain adjustments hereinafter described. l Mounted upon thebent portion 61 a of the bar 60 is a bracket 68 held in position by a clamping bolt 69. This bracket 68 serves as a bearing, as will appear below. A turntable is shown at 70 and is provided with the usual felt surface 71 for supporting the record disks. a This turntable is mounted upon a shaft 72 which extends directly upward"l through the turntable and which is journaled upon thebar 57 a and abearing 57h. Mounted upon this shaft is a pulley 73 whereby it and the turntable are rotated continuously. The upper end of the shaft 72 is provided with a boss 74 which is engaged by a rod 75. The lower end 76 of this rod is so shaped. as to fit over thc boss 74, as will be understood from Fig. 2. The rod 75 is provided with a portion 77 which is engaged by a clip 78 so as to hold the parts in position. By grasping the rod 75 it may be extricated from the clip 78 and moved upwardly, or, if need be, entirelyT removed from the machine in order to facilitate the removal and replacement of the record disks. n 95 is ivotally connected at its outer end with A drum 7.9 is mounted rigidly upon a revol a ro 100, the latter being'in turn ivotally luble stub shaft 80 and is disposed immediconnected with a sliding'rod 101. his sli ately above a s ring barrel 81. A cord 82 is artially wound upon the drum 79, this cord eing also partially wound upon a spool 88 l secured upon a shaft 83. Mounted upon the shaft 83 is a spiral wire 84 serving as a screw thread and rigidly connected at its ends with the shaft 83. A hand crank 85 is mounted upon the upper end of the shaft 83 for the purpose of turning the same at will. Mounted rigidly upon the shaft 83 is a box 83a', and pivoted upon the latter is a awl86 ada ted to rock vertically. This pawl) is provide upon its upper surface with a leaf spring 87 which .engages the s ool 88 secured upon the shaft 83. The paw 86 is provided with a portion 89 projecting downwardly, and disposed partially within the path of this ortion are two bosses 90, 91 carried by a sfide 92 andrigid in relation to the same. These two bosses serveas limiting stops to prevent thev rapid rotation of the pawll 86. The slide 92 is adapted to be actuated within certain limits along the upper end of the bar 60. As shown in Fig. 2, the slide occupies its extreme limit to the right. If, now, the slide be moved slightly to the left, the boss `90 will disengage the portion 89 ofthe pawl 86, and this pawl under tension of the cord 82, tends to rotate. It makes half a revolution and is stopped by the boss 91 engaging the portion 89. When, therefore, the slide 92 is moved back -into its original position indicated in Fig. 2, the pawl 86 makes a second half revolution. Each com lete revolution of the sli-aft 83 and threa 84 is therefore effected, or rather permitted, by a movement of the slide 92, first toward the left and' next toward 65,- the right, according to Fig. 2. Lugs 93 are ing rod is supported at its upper end by a slotted plate 102 connected rigidl7 with the u er frame 59 and 'supporte thereby. T ie shaft 45 is provided with three cams 103, 104, 105. The cams 103 and 105 are socalled snail cams (see 105, Fig. 6), while the cam 104 is what we designate as a roller cam, it being provided with rollers 106, 107. The roller 107 -is a little in advance of the roller 106 in the general direction of rotation. All of the cams are for the purpose of actuatin different movable parts, as hereinafter escribed.

A sound box 108 (see Figs.l 13, 14, 15) is providedwith a needle holder 109, and Aa needle 110 is secured temporarily within the holder for the purpose of engaging the surface of the disk record. .'The needle holder is provided with ay funnel-shaped opening 111 to facilitate the entrance of the blunt end of the needle. This opening'111 merges into a slot 1-12, aswill be understood from- Figs. 14, 15. A lever 113 is provided with a head 114of the shape shown in Fig. 15, andthis head is adapted to engage the blunt end of the needle 110 for the purpose of ejecting the needle from the needle holder. The lever 113 is mounted upon apivot 115 and is provided with a portion 116 extending outwardly from this pivot. When the portion 116-is moved upward according to the view shown in Fig. 15, the needle-110 is ejected.

118 of the sound box and servesto temporarily secure the needle holdervin a definite position, as hereinafter explained, for the purpose of 'facilitating the changing of the needle. A needle bar is shown at 1.19 and is sof icc

A guide plate 117 is mounted upon a portion 125 connected with the needle holder. The needle holder 109 is provided with a revoluble bolt 120 provided with a cross pitch thread 121, smooth cylindrical point 122. The latter engages the needle 110 for the purpose of holding it temporarily in position. A spring 123 is provided with portions 123% 123", whereby it isv secured in position. This spring is wound spirally around the bolt 120 and normally holds it in such position that the point A122 presses against the needle 110 with suflicient firmness to hold it in position. Mounted upon the bolt 120 is a sleeve 124 into which extends a screw 125 engaging the bolt 120. This clamps thc sleeve 124 and bolt 120 rigidly together. The sleeve 124 is provided with an arm 126 shaped substantially like a horn, as indicated in Fig. 13. The aim 126 normally engages a limiting stopv 127 having the form of a spring hook. Whenever the arm 126 is raised, as

indicated by dotted lines in Fig. 13, the bolt p 120 (see Fig. 14)

is turned, and the needle 110 is dropped.' The ends 123, 123b of the spiral spring 123 are secured respectively to the arm 126 and the needle bar 119, as will be understood from Fig. 13. 110@ for receiving the needles dropped one at a time after using, is mounted upon a bracket 1101). For this purpose, a plate 110c isconnected with the needle box and is placed. flatly against the bracket 1101, and secured to the same by a screw 110d. The plate 110c is also bent slightly -over the top of the bracket. By removing the screw 110 d, the needle box may be removed foi the purpose of throwing out the needles.

A phonographic tube is shown at 128 and is pivoted at the point 138a to the braces 129. The tubo 128 is free to accommodate itself to diil'erent parts of the record, and also to allow the needle holder and its accompanying parts to bc shifted for the purpose of changing the needle. The phonographic tube 128 engages a rest 130 and is connected by a flexible. coupling 131 with the horn 132. The horn is supported at its larger end by a rest 133 (see Fig..2) this rest being mounted rigidly upon a rod 134 which is bent at different angles upon itself, as at 135, Fig. 8, and pivoted in bearings 136. These bearings are integral with a plate 137 secured to the framework. By pushing the rest 133 back or forth, the horn 132 can be elevated or lowered within reasonable limits. It is for this purpose that we mount a portion of the rod 135 in bearings 136, `as indicated in Fig. 8.

A post 138 is provided. with outwardly extending portions 138, the'post together.

with these parts being of a general Y- shape. The rest 130 is pivoted intermediate of the portions 138L of the post. The top of the post 138 .is provided with a pivot 139. and its bottom with and further provided with a A needle box Fig. 11). A bracket 141 engages the pvot 139 which in Fig. 11. Similarly the pivot 140 extends downwardly into a rod 142 supported rigidly upon the framework. Connected securely with this frod 142 is another rod 143 bent into the shape indicatedin Fig. 1l. Mounted upon the upper end of this rod is a supporting sleeve 144 constituting a bearing for a small portion of the horn 132. A leaf spring 145 engages the horn 132 and is provided with a portion 146 secured to the rod 143. This portion 146 is bent upwardly at 147 so as to form ears for the purpose of holding the lower end of the spring 145 rigid in relation to the bar 143. A bolt 148 extends through the bar 143 and the spring 146. This bolt is encircled by a spiral spring 149. A nut .150 is threaded and fitted upon the lower end of the bolt 148 the latter being threaded likewise. By turning the nut 150 the spiral spring 149 is compressed or relaxed to a greatei' or lesser extent, as desired, thus affecting the degree of pressure exerted by the leaf spring 145, serving as a means for controlling the tension of this spring.

A rod 151 is connected rigidly with the ost 138, the latter being provided with a liig 152 for the purpose of making the connection between the rod 151 and the post rigid. The rod 151 extends toward the center of the machine (see Fig. 8) and pivotally connected with it is a weight holder 153 of substantially U-shape. A weight -154 is rigidly secured upon this weight holder. This weight is provided with a roller 155 which rests upon a leaf 156 constituting a track therefor. This leaf inclines downwardly so that the weight 1.54 normally tends to draw the rod 151 toward the lower end of the leaf 156. The leaf 156 may be bent to dill'erent angles, as desired, so as to practically adjust the pull exerted by the weight 154. A bracket 157 is mounted rigidly upon the rod 151 `and along the rod 151 is moved by the weight 154. A rocking shaft 158 is mounted in bearings 159, 160, these bearings being integral with slides 160a (see Fig. 8). A portion 161 of the rocking shaft 158 is bent upwardly and forwardly and is located within the path of the bracket 157, so that when the bracket is moved by 158 is turned la little distance. A portion 162 lof the rocking shaft 158 extends beyond the bearing 160 and is bent outwardly. A rocking lever 163 is pivotally mounted upon a support 164, the latter being free to turn upon a pivot 165. The lever 163 is provided with a blade 166 of arcuate conformity. This blade normally occupies a position almost coinciding with a part of the path of a boss 167, which is mounted upon the under side of the turntable. The parts are so another pivot 140 (see A arranged and adjusted, however, that unless action of the weight 154 the rocking shaft extends through it, as indicated the portion 1.62 of the rocking shaft 158 is in its uppermost position, the blade 166 is not quite within the path of the boss 167. Our idea is to have the blade 166 raised by action of the rocking shaft 158 into such position that the blade may be struck by the boss 167, owing to the revolution of the turntable. The support 164 is provided with a lug 168 which is adapted to enter the notch 48 of the cam 47. A counterweight 169, adjustable relatively to the lever 163, enables this lever to be so arranged that comparatively little eliort exerted by the part 162 of the rocking shaft`158 will raise the blade 166 into the pathof the boss 167; see Fig. 7.

e A spring170 is wound upon a lever 1703, and this lever is integral with a shaft 170b,

which is journaled in bearings 170c and free to rock. The lever 1706*, acted upon by the spring 170, normally holds thev lug 168 in the notch 48 of the cam 47.- In doing this the spiral spring tends to force the lever 163 into such position that the blade 166 will intersect the path of the boss 167, but until the cam 47 turns into suoli position that the lug 168 can enter the notch 48 the lever 163 must occupy the positioneindicated by dotted lines-in Fig. 8. The instant, however, that the lever is free to move (owing to the fact that thel lug 168 passes into the notch 48) it springs into the position indicated by full lines in Fig. 8. Even thisl does not quite enable the boss 167 to trip the lever, for the reason that the bladey 166 is too far below the boss. Vhen, however, the rocking shaft 158 is turned, the portion 162 raises the blade 166 directly into the path of the boss 1 67. The lever 163, it will be understood, has two motions; that is to say, it turns slightly in two planes intersecting each other (Fig. 8). The lever may be turned from the position indicated by dotted lines, to that indicated by full lines and vice versa, and it may also be rocked so as to raise and lower the blade 166. When in its lowermost position it engages the rest 171. .The cams 105 upon the shaft 45 is engaged by a roller 172, this roller be-Q ing mounted upon a spring bar 173 which is provided with a shelf 1 7 4 (see lower right hand portion ofFig. 5). `A spiral :spring 175 is connected 'with the shelf 174 and pulls the same directly. A hook 176 formed at the lower end of a bar 177 loosely engages the under side of the spring bar 173 which is bent for this purpose,- as will be understood from 4. The bar 177 is pivotally mounted uponlinks 178, 179,-these links being journaled upon the upper frame 59. A spiral spring 18() is connected with this frame and with the bar 177. This spring tends'to nor- 1 mally hold thebar 177 in ltshighest position, and thus cause it to press gently against the vunder side of the'l spring bar 173. The ten` sion of the spring 180, however, is not suf I upon the bar 177 is a spring finger 181 which extends to the left according to Fig. 4, so as to bc approached quite closely by the lever 126. Mounted below the spring finger 181 is a spring rest 182 which is at times engaged by the spring inger 181. A bracket 183 is mounted rigidly upon the upper frame 59 and supports two guide4 plates 184, 185,y

as indicated in Fig. 4, and extending par tially into the path of the sound box. The rocking shaft 187 is provided at its other end with a crank 189. Journaled uppn this crank is a bar 190. A spring 191 is connected with this bar and also with the upper frame 59. LA link 192 is pivotally connected with the upper frame and with the bar 190. The bar 190A terminates at its lower end in a hook 193 which extends out under a spring bar 194 provided with a shelf 195. A stout spring 196 is connected with this' shelf and normally tends to pull the same downwardly. The spring 191 is considerably weaker than the spring 196 and merely holdsthe bar 190 up toward the spring bar 194. AnV adjusting` screw 197 extends through the spring bar 194 and also through a thumb nut 198. By loosening the thumb nut the adjusting screw 197 maybe raised or lowered and then tightened in position by tightening the thumb nut In this manner the play of the hook 193, and consequently of the bar 190, may be regulated at will in such manner that the height to which' the shelf 195 may be raised can be regulated at will. A roller 199 is mounted upon the spring bar 194 andengages the cam 103, which, as above described, is secured upon the revoluble shaft 45. Pivotally mounted upon lthe shelf 195 and depending therefrom is a pawl 200 carrying at its lower end a weight 201. Brackets 202, 203 are mounted rigidly upon the upper frame 59, and secured to these brackets is a substantially Z-shaped bar 204. To this 1 207 vis mounted upon the. lower end of this slidey and spaced therefrom by a spacing block 208.y The pawl 200 hangs partially rwithin the path of the hook 207, so that whenever the shelf 195 descends, the pawl 200 erga'ges the hook 207 andpulls the slide o iquely downwardly.

ficient to raisev the spring bar`173.l Mounted The upper end f the slidex206 carries a* mounted within this link is a slide 213 prol purpose of guiding the sound box. For this rigidly u on the needle wheel.

head 209 provided with ears 210, 211. Journaled within these ears is a link 212 and vided with shoes 214 which engage o l positely disposed ortions of the link. The ower end of the slide 213 is provided with a plate 215 having a lug 216 integral therewith, this lug being bent slightly upward, according to the' view shown in Fig. 4. A pin 217 is mounted rigidly upon this lug and extends obliquely upward through a spiral spring 218, and also through an ear 219 which is rigid upon the head 209. The iit of the pin 217 within the ear 219 is quite loose so that some little play of the pin within the ear is afforded.

A shaft 220 is journal'ed within the head 209 and is encircled by a spiral spring 221 (see Fig. 20,) which is secured thereto by a pin 221 a. The lower end of this shaft is provided with a shoulder 220a and is journaled in a bracket 220k. A lug,212a mounted upon the link 212 (see Fig. 21) is adapted to engage the shoulder 220a. The upper end of the shaft 220 is provided with a reduced threaded portion 222 upon which iits a nut 223. This shaft 220 extends through metal disks 224 225, a rubber disk 226 and another metal disk 227 arranged as shown in Fig.'20. Holes 228 extend through the disks 226 and 227 and into the disk 225, which is coned out to receive the sharp end of the needle. Into the holes 228A are inserted a number of needles 110, spaced equidistant. As each needle is thus centered in the bottom of the hole in which it rests and is also centered by the rubber disk 226 because of the resiliency oi' the latter/the needle is held straight, but is not rigid while in the needle wheel. The disks 224, 225, 226 and 227 together constitute a member which we designate as the needle wheel. A stop pin 229 is mounted A nee le chute 230 is provided with a plate 231 integral with it (see Fig. 21) and this plate is adjustably connected by a screw 232 and a nut 233 With-the head 209. A washer 234 is dis osed immediately below the needle wheel. plate 235, adjustable by aid of a. bolt 235a and nut 235", is providedwith an ulpwardly projecting portion 236 having a s ot 237. This plate with its slot isffor the purpose the plate 235 may at times be raised into such position that the plate 117 upon the sound box may be disposed Within the slot, as will be understood from Fig.`4.

In order to facilitate the exchange of the needles from the needle wheel to theneedle holder, they are brought in succession to the determinate point by aid of a V-sha ed mutilation V238' (see Fig. 7) in the nee e chute. The needle Wheel can only turn to such an extent as will bring one of the needles into the bottom of this V-sha ed mutilation, and when this needle is pul ed out, the'needle wheel is free to turn slightly so as to bring the next successive needle into the same position.

Mounted u on one end of. the shaft 45 is a crank 239. Jpournaled upon the other end of this crank is a pitman 240, the lower end of this pitman extending downwardly and being ournaled upon a bracket 241 carried by a slide 242. This slide also carries another bracket 243 and extending through both of these brackets is a slide rod 244. This slide rod is slidably mounted near its lower end in a bearing 245. The upper end of the slide rod is connected rigidly with a late 246 having a central slot 246a vand eing slidably mounted in bearings 247. Mounted upon the upper end of the plate 246 is a bracket 248 extending horizontally therefrom. A horizontal arm 249 is mounted upon this bracket and is provided with a slot 250. Extending` obliquely upward through this slot is a movable arm 251 which is mounted .upon a pivot pin 252 secured rigidly u on the lower portion of the bracket 248. he arm 251 is free to swing within limits allowed by the slot 250. A plate 253 is mounted upon the horizontal arm 2419 and is provided with a slot 254, and a screw 255 extends through this slot and into the horizontal arm 249. By aid ofthe screw 255 and slot 254 the plate 253 may be adjusted within reasonable limits upon the horizontal arm 249. The plate 253 is provided with a lug 256 integral therewith, and this lug is engaged by a pawl 257, which pawl is mounted upon a pivot pin 258 carried y the plate 253.) A spring 259 is wound partially around the pin 258 and is secured rigidly thereto, this spring being also secured to the pawl 257, as will be understood from Fig. 9. The upward limit of movement of the awl 257 is made by the lug 256. The paw is thus free to swing downwardly upon the pivot pin 258 as a center, until .the pawl reaches such position that its upper surface is flush with the upper surface of thel arm 249. Mounted upon the slide rod 244 is a bracket 260 secured rigidly in position b a bolt 261, and by aid of this bolt the bracket 260 may be adjusted upon the rod 244. A pawl 262 is pivotally mountedl upon the' racket 260 and is connected therewith by a spring 263 in such manner that .the upper portion of the pawl 262 normally stands vertical. This pawlfis mounted upon a'pivo't 264 and is provided-with .a lug 265. Disposed adjacent to the path of thislug is a slide 266 provided with a slot 267. An adjusting screw 268 extends through this slot and into the frame menber 25. The lower end of the plate 266 is provided with a lug 269, this lug being directly in the path of the lug 265 of the pawl 262.

The rotation of the shaft 45 causes the crank 239 to turn, and the pitman 240 actuated by this crank c'auses the sliderod 244 to the stationary bracket 269, and the pawl the down stroke given by the crank 239.

rod 27() is provided with a wide flat portion i guided. This slide moves upward at the saine instant as the rod 244.

being com reciprocate vertically. The slot 246a in the plate 246 is not of suflicient length, however, to allow the'rod 244 to perform a stroke of double the length of the crank 239; that is i to say, the rod 244 and the plate 246 move upwardly until stop ed by tie engagement o the lower end of t e slot 246a against the shaft 45. At the instant when .this takes place the lug 265 lodges against the lug 269 (see lower left-hand portion of Fig. 9), and the p'awl 262 is tripped. This pawl in 'the lower portion of the stroke of the rod 244v en gages a lug 241El upon the plate 241. TWhen, however, the pawl is tripped, as just stated (see Fig. 9), it disengages the lug 241% and the slide 242 being now free of the rod 244, simply continues its upward travel in consequence of motion given it by the crank 239. The movement just described may be briefly summarized by saying that the slide 242 has the motion which would ordinarily be expected from the crank 239, and during a part ofthe stroke of this slide it carries 'according-to Fig. 9, so as mately reaching its extreme with it the rod 244, dropping this rod at a definite point and picking it up again upon the down stroke of the rod 244. This picking up of the 'rod 244'by the downward, movement of the slide 242, takes place because the instant the slide 2.42 reaches the i bracket 260 and carries it downward, the! portion 265 of the pawl 262 is lreleased from 262, u nderirnpulse of the spring 263, clicks again into its normal position, thus engaging the lug 241 a of the plate 241 and causing the slide 242 and the rod 244 to finish, as a unit,

Disposed adjacent to the slide rod 244 and parallel therewith is another slide rod 270, the latter toward its bottoml extending through' a bearing 271 and being provided j with a toe 272. A spiral'spring 273 of the so-called extension type is connected with the toe 272 and is also secured to an ear 274 mounted upon the framework. The slide 270EL which enables it `to be more easily rod 270 has a motion very much like that of the slide rod 244. It starts upward at the same instant as the slide rod 244 andlfhen the latter is stopped as above described, the slide rod 270 is stopped at the same instant. Hence, the horizontal arm 249, which is supported partly by the plate 246 and partly bythe slide 'rod 270,'has an analogous motion. 1t

A pitman rod 41008*, which is pivotally connected with the slide 242, is provided with a sliding head 1001, in which is mounted .a spiral compression spring 100', the latter being always under more ory less tension, and

ljust described causes rises and moves slightly arm 2,51 is 1n its extremejposition at the ressed Whenever the swillllflg to firmly hold the phonographic tube 128 while the sound box receives a needle. The upper end of the sliding head 100b is pivoted at its upper end to the arm 251. Since the slide 242has a movement-equal to double the-length of the crank 239, it follows thatthe rod 100n and the arin 251 actuated by it do not stop in their movements except at the limits of the stroke of `the crank. The net result is that when the horizontal arm 249 is in its lowermost position, the arm 251 occupies its farthest position to the right, according to Fig. 3. vThe horizontal arm 249 and the arm 251 start upwardly `together, still occupying the same relative position. to a stop; yet thel arm 251 does not stop but continues its upward motion now swinging upon the pivot pin 252'as avcenter, ultiposition to the left, as indicated in Fig. 9. This operation also brings the sound box from the center of the record into a position favorable for setting the needle. Furthermore, the action the needle to move into suitable position to engage the record at the starting point thereof. This movenient is repeated with every revolution of the shaft 45.

The crank 239 carries a pin 275 extending inwardly toward the framework, as indicated at the left lof Fig. 5. This pin is in close proximity to a star wheel 276 which is mounted upon a stub shaft 277. This star wheel is provided with pawls 278 mounted one upoii every second tooth by aid of a screw 2798, as indicated in Fig. 9. Partially obstructing the path of each pawl 278 is a lever 279 mounted in brackets 280. The lever 279' is integral with a shaft 281, the other end of this shaft being provided with a crank 282 integral with it. Each time the lever 279 is thrown outward the crank 282 outward from the center of the machine.

A bracket 283 (see lower right-hand corner of Fig, 4) is adjustably mounted, and for this purpose a screw 284 passes it. By loosening the screw 284 and moving the bracketendwise, as indicated by fulland dotted lines in Fig. 4, the arm279 may be The arm 249 comes directly through moved .into or out of the path of the several starwheel is 'turned one step.

Referring ,new to Fig. portion, -a bracket 285, of substantially .U- shape', 'is mounted. rigidly upon the upper frame 59 and supports a Apin 286 extending of the star wheel ijs l accomplished step by step.. Each time the shaft 45 makes a complete revolution',- the 5,'llower central I.

directly through it. Journaled upon this pin by means of bearings 287, 288 are two evers 289, 290,I which areengaged respectively by the rollers 107, 106 carried by the roller cam 104. Each time the shaft ,45 turns, these two levers are lifted upward, the movement of the lever 289 being slightly earliergthan that of the lever 290. Each time the shaft makes a revolution', therefore, a roller 291, carried by the lever 290, being normally in contact with the plate 215 of the slide 213 (see lower middle portion of Fig. 4), and being raised by the under side of the roller 106 against the under side of the lever 290, causes the slide 213 to move obliquely upward according to the View shown in Fig. 4. As the spring 218 will resist considerable pressure before eing compressed to any great extent, the slide 206 isv raised obliquely upward, carrying ahead of it theV needle wheel. The latter stops in such position that one of the needles is inserted di rectly into the needle holder which at this step 1s always empty. The lever 289 engages the under side of a portion 293 of a link 292, thus raising this link. In the meantime the cam 105 raises the shelf 174 so that the portion of the link underneath this shelf is entirely clear of the same for the moment. As theshelf 174 is raised by the action of the cam 105 against tbe roller 172, the-rod 177 moves u ward in consequence of the constant pull oi) the spring 180 u onit. The shelf 174 reaches approximatey its highestposition before the lever 289 begins to rise, as will be understood from Fig. 4. The shelf pauses for amoment in its highest position and is overtaken by the horizontal portion 294 of 'the link 292 which rises into engagement with it. For convenience the link 1s provided with the double portion 293 of suflicient lever 289.

breadth to constitute a broad'bearing for the The shelf, being released by the rotation of the cam, is drawn abruptly downward by the tension of the s ring 175 and carries with it the link 292 an( all parts immediately dependent upon this link for their motion. 'lhe slide rod 101 being con, given a recipro-4 nected with this link is thus eating vertical motion which, like thevrotation of the sh aft 45, is by no means constant. Connected with the link 2 92 is a spiral spring 292' St which retracts'it into normal position whenever it is otherwise free.

The lower end of the slide rod 101 is integral with a plate 296provid'ed with a slot 297, as shown in Fig. 10. The slide rod 101 is slidably connected to bracket 1101. For this purpose a bolt extends through the slot 297 and into bracket 11101. Said bracket is rigidly mounted upon a frame 59 and holds the needle box 110"L integral with a plate 110c by a screw 110al (see Fig. 4). The plate 296 is further provided withl anexte'nsion 295 bent substantially into U-shape as indicated in Fig. 10. A lever 29,9 is mounted upon the rod 101 by aid of a pivot' Y in 300. The plate 296 is provided wlth a ug 301 which normally engages the upper surface of the lever .limit of its movement, indicated .inFig 6. A substantially U-shaped lever 305 1s Journaled within the bearing 306. A portion 307 of this lever extenlds u wardly from the bearing and engages the sli e 213 at the inner side thereof so that whenever the lever 305 is moved outwardly, the slide 213 and its immediate mountings likewise swing outwardly, being journaled in the brackets 210 as above described, for this purpose (see lower central portion of Fig. 4).

By adjusting the bracket 283 (see lower right-handy ortions of Fig. 4) as indicated lby dotted ines, and the lever 279 being moved into the path of the pawls 278, it follows that each partial revolution of the star wheel 276 in causing one of the pawls to move the lever 279 outwardly, must necessarily cause the crank 2,82 carried by the shaft 281 to engage the inner surface of the U-shaped lever 305 so as to throw In doing this the slide 213 and link 2l2swing outwardly as described, so that when the roller 291. rises, as above described, the slide 213 is not lifted and consequently the needle wheel is not moved upward. It follows, therefore, that the operator, by merely adjusting the bracket 283, causes the needle wheel to beperiodic'ally moved upward or t0 remain stationa as desired. At the instant when the s "de 213 is pulled outward, the link 292 is likewise pulled outward; this is done by theU-shaped rod 305. Hence, the upward movement of the plunger rod 101, with its dependent parts, is prevented. As a consequence, the needle is not ejected, and no record now drops upon the turntable. The needle wheel, the needle ej ector and the record-dropping apparatus are disengaged for the time being. from control of the shaft 45. The result is that each record is layed twice in succession with one needle efore the next successive record is allowed to drop upon the turntable. This will be easily understood by bearing in mind the action of the pawls 278, located one each upon every second tooth of the star wheel 276.

A ,s acing sleeve 307 a encircles the bolt 277 o the star wheel 276 (see lower righthand ortion. of Fig. 24). A bracket 308 partially sup ortsthis lsleeve and also su ports one en of the bolt 27 7 Sprin was ers 309 and a nut 310 are used or t e purthis lever outwardly.
